GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(618, 693) = 142758
GCD(618, 693) = ( 618 x 693 ) / 142758
= 618 / 693
= 618
Step2:
LCM(3, 720) = 720
GCD(3, 720) = ( 3 x 720 ) / 720
= 3 / 720
= 3
Step3:
LCM(3, 222) = 222
GCD(3, 222) = ( 3 x 222 ) / 222
= 3 / 222
= 3
So, Greatest Common Divisor of 618, 693, 720, 222 is 3
